Description

[Detailed Description of the Invention] The present invention relates to an oil spill prevention device that is installed using a manhole or the like located in the middle of a drainage channel for discharging wastewater into the sea.

Conventionally, this type of oil spill prevention device uses a fixed separator to separate floating oil.

When this type of separator is applied to areas where there are large vertical changes in water level, such as during the ebb and flow of the tide, the height of the separator must be sufficient to satisfy the vertical width of the water level. It was severely hampered.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to be able to effectively separate oils by applying it to areas where the water level changes significantly, and to easily remove oils. The present invention is intended to provide an oil spill prevention device.

Hereinafter, the present invention will be explained based on an embodiment shown in the drawings.

In the figure, reference numeral 1 denotes a container body, and an inlet pipe line 2 and an outlet pipe line 3 are connected to a side wall 1a of the container body 1 so that they can communicate with each other.

The container body 1 has an internal space 1b which is higher than the pipes 2 and 3.

Further, within the container body 1, an oil adsorption member 5 is arranged so as to block the flow of liquid from the inlet side pipe line 2 to the outlet side pipe line 3, and is positioned near the liquid surface by the buoyancy of the float 4. is provided.

The oil adsorption member 5 is suspended below the float 4,
The float 4 and the oil adsorption member 5 are arranged in a band shape over the entire length of the container body 1, and are arranged in a manner to intersect the flow of liquid from the pipe line 2 to the pipe line 3 at an angle. It is designed so that it protrudes above the liquid level.

The float 4 may be of any type as long as it generates sufficient buoyancy to position the oil adsorption member 5 near the liquid surface, and an air bag or the like with air sealed therein may be used.

Further, the oil adsorption member 5 may be any member as long as it can adsorb and hold oil, and commercially available products can be used.

Further, a guide mechanism 6.degree. 6 for guiding the vertical movement of the oil adsorption member 5 is provided inside the side wall 1a of the container body 10.

As shown in detail in FIG. 3, this guide mechanism 6 includes a plate-shaped arm 9 made of, for example, synthetic resin, which is removably fixed to the end holding portion 1 of the float 4 with a bolt 8 and protrudes outward. A cylindrical slider 10 made of, for example, synthetic resin is fixed to the tip of this arm 9 with an adhesive 11, and this slider 10 is accommodated in an inner hole to guide vertical movement, and the arm 9 is configured to move vertically. A guide tube 13 having a vertically elongated slit 12 which is movably penetrated and opened over its entire length is fixed to the side wall 1a of the container body 1 with nails 14 in a vertically elongated manner.

The guide tube 13 has a length that can accommodate changes in water level during the ebb and flow of the tide.

To explain the operation of the device configured as above,
For example, when seawater flows back from the outflow pipe 3 at high tide and the water level A inside the container body 1 rises, the oil adsorption member 5 is raised by the float 4 and is located near the water surface A, and the oil The adsorption member 5 is not moved in the direction of water flow by the guide mechanisms 6, 6, and adsorbs and holds the oil floating on the water surface A at this position.

Conversely, when wastewater flows out from the outflow pipe 3 at low tide, the oil adsorption member 5 moves down together with the float 4 as the water surface A falls, and the oil adsorption member 5 6, it does not move in the direction of water flow, and at this position it adsorbs and holds the oil that has surfaced on the water surface A.

Therefore, oil accumulated on the upstream side of the container body 1 such as a manhole is blocked by the float 4 and the oil adsorption member 5, and is prevented from flowing downstream from the outflow pipe 3.

Incidentally, if the oil adsorption member 5 is periodically taken out from inside the container body 1 and replaced with a new one, the oil can be easily removed together with the oil adsorption member 5.

At this time, the oil adsorption member 5 moves the mover 10 into the guide tube 13.
It can be easily taken out by pulling it out from the upper end opening 13a.

As explained above, the oil spill prevention device according to the present invention includes a container body having an internal space connected to an inflow side pipe line and an outflow side pipe line and higher than each of these pipe lines, An oil adsorption member arranged to block the flow of liquid from the inflow side pipe to the outflow side pipe and positioned near the liquid surface by the buoyancy of the float, and a guide that guides the vertical movement of this oil adsorption member. Because it is equipped with a mechanism, in places where the water level changes greatly, such as during the ebb and flow of the tide, the oil adsorption member moves up and down from the float as the water surface rises and falls, and moves from the inlet pipe to the outlet pipe. Since it blocks the flow of oil into the canal, it can be applied to areas where the water level changes significantly to effectively separate oil, and if the oil adsorption member is removed from the container body, the oil can be adsorbed. It can be easily removed together with the parts.
